  • 1998.5-2003 Cummins 5.9L ISB (275/300HP) VP Fuel System
  • 1998.5-2005 Cummins 8.3L ISC (315/330/350HP) CAPS Fuel System
  • 1998.5-2003 Cummins 8.9L ISL (380/400HP) CAPS Fuel System

This heavy duty adjustable fuel pump is designed to meet the demands of the added strain of a performance module on the CAPS fuel system. The CAPS fuel system is known to be a weak fuel system as the factory lift pump only engages for the first 30-45 seconds after the key-switch is engaged. After this, the CAPS pump "pulls" the fuel and acts as the only pump in the system. By adding this heavy duty pump, not only are you taking away a lot of stress on the CAPS pump but you are also providing a steady flow of fuel that will help cool and lubricate the pump to increase the reliability and longevity of the CAPS pump. This adjustable pump is rated at 95 gallons of diesel fuel per hour and come preset at 15 PSI. Using a 1/8" Allen plug, you can make a quick clockwise adjustment to increase pressure or counter  clockwise to decrease pressure.
